Networking Issues

This section covers how to solve problems related to how your printer, network, and iPad communicate.

If the Printer Setup screen displays this error, it means either your iPad is connected to the wrong network, the printer is disconnected from your router, or the printer cannot obtain an IP address.

Follow the steps below to troubleshoot this issue. After performing each step, check to see if the problem is resolved.

  1. See if the iPad is connected to the correct Wi-Fi network.

    Open Settings, tap Wi-Fi, and make sure the iPad is connected to the same network as the printer.

    If the iPad often connects to the wrong network, visit our Settings Troubleshooting guide for help.

Star SP700 Status Light Issues

This section covers issues communicated by the status lights on the front of the Star SP700 ticket printer.

The ERROR light is blinking and the POWER light is solid.

An ERROR light blinking about once per second means the printer has either run out of paper of or is about to run out. If the ERROR light is blinking much quicker, it means there may be a paper jam.

  1. Power off the printer.
  2. Push the lever to open the printer's back cover.
  3. If the printer is out of paper, load a new roll and close the cover on the paper.
    • The paper must be loaded so it feeds up from the bottom of the roll.
    • Visit the ShopKeep Store if you need to buy more paper.
  4. If there is a paper jam, clear the jam and close the cover.
  5. Power the printer back on.

The ERROR light is solid and the POWER light is solid/flashing.

This combination of lights means one or both of the printer’s covers are open.

  1. Close the front and back covers to resume normal operation.
  2. If neither cover is open, open and close both covers to reset this warning.

Both the ERROR and POWER lights are blinking.

This error occurs when the printer is no longer receiving an IP address from your network.

  1. Follow these steps above to troubleshoot this issue.

The ERROR light is off, but the POWER light is blinking.

This combination of lights indicates the printer has overheated.

  1. Wait a few moments for the printer to cool down.

    Normal operation automatically resumes once the printer has cooled.

None of the Star printer's lights are lit.

If no status lights are lit, it means the printer is either turned off or not receiving power.

  1. Toggle the power switch to check if the printer is powered off.
  2. Make sure the power cable is plugged securely into the back of the printer.
  3. Plug the printer into a different power outlet.

Epson TM-U220B Status Light Issues

  2. If neither cover is open, open and close both covers.
  3. If the problem persists, power the printer off, wait a few seconds, and power it back on.

The ERROR and PAPER OUT lights are both solid.

  1. Push the lever to open the printer's back cover.
  2. If the printer is out of paper, load a new roll and close the cover on the paper.

Hardware Issues

This section covers problems that may arise with the printer itself, not related to how it connects to your network and iPad.

Tickets are printing very lightly.
